太平岭核电站和三澳核电站分别位于广东省惠州市和浙江省苍南县，各基地规划建设6台百万千瓦级压 水堆核电机组。东方电气集团及旗下企业在"华龙一号"核岛与常规岛的多项关键设备上实现了自主化突 破与批量供货。在反应堆压力容器、稳压器设备研制过程中，东方重机攻克了薄壁防热冲击套管半盲态 全焊透自动 TIG焊接、电加热器套管冷装及防变形焊接等多项工艺难关；在反应堆冷却剂泵研制过程 中，东方法马通实现了关键部件全部国产化，突破了叶轮的流道全尺寸加工核心技术；在核控制棒驱动 机构加工中，东方汽轮机攻克了高精度零件加工、异种材料堆焊等核心技术，实现关键部件全部国产 化。目前，研发团队围绕相关核心技术已进行专利布局。 据悉，两个项目的1号机组投入商业运行后，预计每年每台机组可提供清洁电能达近100亿度，能够满足 100万人口的生产生活年度用电需求，等效可减少标煤消耗超300万吨，减少二氧化碳排放924万吨，相 当于造林2.25万公顷。（陈景秋） 近日，中国广核集团有限公司旗下广东太平岭核电项目1号机组、浙江三澳核电项目1号机组获颁运行许 可证并启动首次核燃料装载，标志其正式进入带核调试阶段。中国东方电气集团有限公司为这两台"华 ...

Core Viewpoint - The achievement of 100% localization of spare parts for the Haiyang Nuclear Power Units 1 and 2 marks a significant step towards the self-sufficiency of China's nuclear energy industry, enhancing the high-quality development of the sector [2]. Group 1: Localization Achievements - The Haiyang Nuclear Power project has completed the localization of key components and materials, transitioning from technology introduction to independent innovation over eight years [2]. - The main pump frequency converter, a critical device for the third-generation passive nuclear power units, has been successfully localized, which previously relied heavily on imports [4]. - The localization of the frequency converter has prevented four instances of unplanned shutdowns, demonstrating its technical performance meets international advanced levels [4]. Group 2: Collaborative Innovation - Shandong Nuclear Power has established an integrated collaboration mechanism involving production, education, research, and application, exemplified by the development of the ultrasonic flow meter for main water supply [6]. - The successful development of the nuclear-grade flow meter has overcome numerous technical challenges and is recognized as a domestic innovation with international leadership [6]. - Partnerships with various institutions have led to the design and manufacturing of core components, fostering an open and collaborative innovation ecosystem [6]. Group 3: Systematic Advancement - Over the past eight years, Shandong Nuclear Power has conducted 60 review and appraisal meetings, resulting in the localization of over 100 spare parts projects [8]. - The company has established a positive development path from "single-point breakthroughs" to "systematic verification" and "scale application," significantly reducing the impact of international supply chain fluctuations [9]. - The achievement of 100% localization of spare parts reflects not only technical capabilities but also an overall enhancement of the collaborative and self-controlled capabilities of the industry [9].
